It was an extremely close race between Universal's The Boss and Warner's Batman v Superman: Dawn of Justice for first place this weekend. The Boss is currently estimated to come out ahead with $23.48 million, but with an estimated lead of only $45,000, either film could ultimately end up in first place this weekend.

Regardless of whether or not it ends up in first place this weekend, The Boss outpaced expectations and performed well with its modest price tag in mind. The Melissa McCarthy led R-rated comedy also proved to be critic-proof this weekend. The film's opening weekend performance was 9 percent ahead of the $21.58 million opening weekend of 2014's Tammy (though it should be noted that Tammy's opening weekend take was softened by a Wednesday debut) and 19 percent below the $29.09 million debut of last year's Spy (it should be noted that The Boss had been widely expected to open below Spy). With this weekend's performance of The Boss, McCarthy continues to remain one of the more consistent box office draws in recent years. McCarthy will next appear in Sony's Ghostbusters, which arrives on July 15.

The Boss started out with $8.11 million on Friday (which included an estimated $985,000 from Thursday night shows), increased a healthy 20 percent on Saturday to take in $9.73 million and is estimated to decline 42 percent on Sunday to gross $5.64 million. That gave the film an estimated opening weekend to Friday ratio of 2.90 to 1. The Boss skewed heavily toward female moviegoers (67 percent) and slightly towards moviegoers under the age of 35 (51 percent). Audience reception to The Boss appears to be lackluster as the film received a C+ rating on CinemaScore and current has a Flixster audience score of just 50 percent. With that in mind, it's quite possible that The Boss won't hold up as well going forward as McCarthy's previous hits have. On the other hand, the film's mentioned strong Saturday hold is an early encouraging sign.

After leading the box office for the past two weeks Batman v Superman: Dawn of Justice fell to a close second place this weekend with an estimated $23.44 million. The blockbuster 3D superhero film starring Ben Affleck and Henry Cavill continued to fall off sharply, as the film was down 54 percent from last weekend. Batman v Superman is now on the verge of reaching the $300 million domestic mark with a 17-day take of $296.69 million. However, as a result of its soft holding power thus far, Batman v Superman is now running just 1 percent ahead of the $294.51 million 17-day take of last year's Furious 7 (which fell 51 percent in its third weekend to gross $29.16 million). With that in mind, Batman v Superman will soon fall behind the pace of Furious 7, especially with Disney's highly anticipated The Jungle Book entering the marketplace this coming Friday.

While Batman v Superman continued to decline sharply this weekend, Disney's Zootopia continued to display strong holding power with an estimated third place take of $14.35 million. The blockbuster 3D computer animated film was down just 26 percent from last weekend. Without taking into account ticket price inflation, Zootopia registered the eighth largest sixth weekend gross of all-time. Zootopia is also on the verge of reaching the $300 million domestic mark with a 38-day take of $296.01 million. The film is now running just 8 percent behind the $320.39 million 38-day take of last year's Inside Out and will continue to make up ground in that comparison going forward. Zootopia already has a current total gross to opening weekend ratio of 3.94 to 1.

Universal's My Big Fat Greek Wedding 2 placed in fourth with an estimated $6.42 million. The PG-13 rated comedy sequel starring and written by Nia Vardalos was down 43 percent, as the film took a hit from the debut The Boss this weekend. My Big Fat Greek Wedding 2 continues to perform towards the higher end of expectations with a 17-day take of $46.75 million. That places the film 6 percent behind the $49.59 million 17-day gross of last year's The Intern (which fell just 26 percent in its third weekend to take in $8.68 million). My Big Fat Greek Wedding 2 will hope to re-stabilize next weekend with the debut of The Boss behind it.

Hardcore Henry rounded out the weekend's top five with an estimated $5.10 million. The low-budget action film from STX Entertainment opened below pre-release expectations and delivered a lackluster per-location average of $1,690 from just 3,015 locations. The trailer for Hardcore Henry had gone over well, especially online, but that reception ultimately failed to get moviegoers to see the film this weekend. Hardcore Henry delivered the lowest debut for STX Entertainment to date in the distributor's young history. The film opened with $2.01 million on Friday (which included an estimated $380,000 from Thursday night shows), declined a concerning 7 percent on Saturday to gross $1.87 million and is estimated to slide 35 percent on Sunday to take in $1.22 million. That places the film's estimated opening weekend to Friday ratio at a fairly front-loaded 2.54 to 1. Much like The Boss, Hardcore Henry doesn't appear to be going over all that well with moviegoers. Hardcore Henry also received a C+ rating on CinemaScore and has a respectable current Flixster audience score of 66 percent.

Faith-based films Miracles from Heaven and God's Not Dead 2 claimed sixth and seventh place with respective estimated takes of $4.80 million and $4.05 million. Sony's Miracles from Heaven was down a very solid 34 percent this weekend, while God's Not Dead 2 was down a sizable 47 percent. Miracles from Heaven passed the $50 million mark this weekend and continues to perform nicely with $53.81 million in 26 days. God's Not Dead 2 has been far less impressive with $13.84 million in ten days and clearly isn't duplicating the word of mouth or the performance of its predecessor, 2014's God's Not Dead, which grossed $21.75 million in its first ten days after falling just 4.5 percent in its second weekend to take in $8.80 million.

Overseas Update:

Disney's The Jungle Book started its overseas launch with $28.9 million from select markets. Top grosses by market included $7.6 million in India, $6.2 million in Russia, $2.6 million in Australia and $2.2 million in Argentina. The film's strong overseas start is another good sign when it comes to this Friday's domestic launch.

Universal's The Huntsman: Winter's War also started its overseas run this weekend. The follow-up to Snow White and the Huntsman took in an estimated $20.0 million from 18 territories. Grosses by market included $4.4 million in the United Kingdom and $3.0 million in Mexico.

The Boss debuted with $1 million from eight territories, including $350,000 from the U.A.E.

Batman v Superman grossed $34 million from 67 markets. That brings the film's current overseas total to $486.8 million and global haul to $783.5 million. Current totals to date for individual markets include $93.3 million in China, $47.5 million in the United Kingdom, $33.7 million in Mexico and $28.3 million in Brazil.

Zootopia took in $22.7 million from 53 territories. That places the film's overseas total at $556.5 million and global total at a massive $852.5 million. Current totals to date for individual markets include $232.2 million in China, $31.2 million in Russia, $29.4 million in France, $28.5 million in Germany and $26.5 million in the United Kingdom.

My Big Fat Greek Wedding 2 grossed $3.3 million from 19 territories. The film's overseas total stands at $24.1 million, while the film's global total is currently at $70.9 million.

Miracles from Heaven took in $1.1 million in its second weekend in Mexico. The film has grossed $5.3 million to date overseas, with $3.9 million of that total coming from Mexico.

In its second weekend of platform release, Paramount's Everybody Wants Some!! had a solid expansion with an estimated $510,000 from 63 locations. That gave the Richard Linklater directed comedy a respectable per-location average of $8,095. Everybody Wants Some!! was up 63 percent over last weekend, when the film was playing in 44 fewer locations. Everybody Wants Some!! has grossed $974,436 through twelve days. The film is scheduled to receive another expansion this coming Friday.

Sony Pictures Classics' Miles Ahead also had a solid expansion in its second weekend of platform release with an estimated $227,411 from 25 locations, for a per-location average of $9,096. The Miles Davis biopic starring and directed by Don Cheadle was up 99 percent over last weekend, when the film was playing in just 4 locations. The ten-day total for Miles Ahead stands at $377,374. Miles Ahead will expand again this coming Friday and is scheduled to expand into moderate release on April 22.

After a healthy three-week platform run, Warner's Midnight Special entered into moderate release this weekend with an estimated $1.16 million from 493 locations. That gave the Jeff Nichols directed sci-fi film starring Michael Shannon a modest per-location average of $2,345 for the frame. Midnight Special was up 110 percent over the previous weekend, but added an additional 435 locations in the process this weekend. Midnight Special has grossed $2.30 million through 24 days and has already surpassed the $1.73 million final gross of 2011's Take Shelter.

Fox Searchlight's Demolition took in a similar weekend estimate of $1.13 million, but did so while playing in 854 locations. That gave the Jean-Marc Vallée drama starring Jake Gyllenhaal and Naomi Watts a lackluster pre-location average of $1,317 over its opening weekend frame. Demolition appears to have been hurt by its mixed critical reviews. The film currently has a 50 percent Tomatometer on Rotten Tomatoes.

In its second weekend, Chongqing Hot Pot took in an estimated $235,000 from 45 locations, for a per-location average of $5,222. The Mandarin-language comedy thriller from China Lion Film was up 16 percent upon expanding into 25 additional locations. The ten-day total for Chongqing Hot Pot stands at $524,987.

Noteworthy debuts in platform release this weekend included an estimated $67,739 for Drafthouse Films' The Invitation (from ten locations, for a per-location average of $6,774) and an estimated $24,341 for The Orchard's Louder than Bombs (from four locations, for a per-location average of $6,085). Respective Tomatometers currently stand at a strong 92 percent for The Invitation and at a modest 67 percent for Louder than Bombs.

Saturday Update: Melissa McCarthy's The Boss dethroned Batman v Superman from the top spot on Friday as the former took in an estimated $8.082 million opening day. By comparison, that's 21.5 percent below the $10 million opening day of last summer's Spy, but is also ahead of many pre-release expectations. Unfortunately, reviews are in the cellar and word of mouth appears lukewarm at best. Look for a healthy opening weekend in the realm of $23 million.

The aformentioned BvS added $6.045 million yesterday, down another sharp 60 percent from last Friday. With $279.3 million in the domestic bank through 15 days of release, the superhero flick is pacing 10 percent behind Iron Man 3 and just 6 percent ahead of Deadpool. BoxOffice projects a third weekend of $21.3 million.

Zootopia continues to hold strong as it eased 38 percent from last Friday to $3.476 million yesterday. With $285.14 million domestically so far, the animated blockbuster continues to thrive as it races toward the $300 million benchmark. Look for a weekend around $12.2 million.

STX's Hardcore Henry landed with $2.01 million on opening day Friday. With a 70 percent Flixster score this morning, action fans are digging it more than critics (53 percent). BoxOffice is projecting an opening weekend around $5.2 million.

Look for official weekend estimates from the studios here at BoxOffice on Sunday morning.

Friday Report: Sources report that The Boss took in $985,000 last night, notably under the $1.3 million Tuesday night start of Tammy -- although that fellow Melissa McCarthy comedy debuted in the middle of summer 2014.

Meanwhile, STX Entertainment reports that Hardcore Henry scored a solid $380,000 from Thursday night's opening shows. That came out ahead of the $340,000 earned by Triple 9 last month, and under the $600,000 taken in by Hitman: Agent 47 last summer. Opening weekend is expected to land in the upper-single-digit millions.

Warner's Batman v Superman: Dawn of Justice took in $2.72 million on Thursday to lead the daily box office for a 14th consecutive day. The blockbuster 3D superhero film starring Ben Affleck and Henry Cavill fell 4 percent from Wednesday and a sharp 65 percent from last Thursday. Batman v Superman was the week's top film with a weekly take of $64.18 million. That represented a very sharp 69 percent decline from the film's opening week performance and brings the film's two-week total to $273.25 million. Batman v Superman is currently running a slim 3 percent on ahead of the $265.35 million two-week take of last year's Furious 7, but is likely to see its percentage lead shrink further over the upcoming weekend.

Disney's Zootopia continued to claim second place with $1.58 million. The blockbuster 3D computer animated film was up 5.5 percent over Wednesday and down 51 percent from last Thursday. Zootopia placed in second for the week with $25.72 million. The film was down just 33 percent from the previous frame and has grossed a massive $281.66 million in five weeks of release. That places the film 23 percent ahead of the $229.23 million five-week yskr of 2014's The LEGO Movie.

Universal's My Big Fat Greek Wedding 2 held steady in third place with $0.850 million. The long-awaited comedy sequel starring and written by Nia Vardalos decreased 5 percent from Wednesday and 48 percent from last Thursday. My Big Fat Greek Wedding 2 passed the $40 million mark yesterday and has grossed $40.33 million in two weeks. The film took third place for the week with $14.97 million, which was down 41 percent from the previous week.

Faith-based films Miracles from Heaven and God's Not Dead 2 claimed fourth and fifth place with respective daily grosses of $0.558 million and $0.460 million. For the week, Pure Flix's God's Not Dead 2 placed in fourth with $9.78 million, while Sony's Miracles from Heaven finished very closely behind with $9.73 million. Respective total grosses stand at $49.01 million for Miracles from Heaven in 23 days and at a softer than expected $9.78 million for God's Not Dead 2 in one week.

Friday Afternoon Update: In a case of triple déjà vu, Captain America: Civil War took home top spot for the third week in a row, narrowly beating out Suicide Squad by 100,625 to 90,484 total tweets. It would seems as though the Spider-Man x-factor has given Cap's appeal a big shot in the arm. Considering that the second film improved by 50% over the first opening we here at Box Office feel comfortable its a feat that he can repeat again with the third film and take it to over $150 million. Superhero adaptations continue to dominate the box office and with over two dozen such films on the upcoming release schedule its clear that the genre is one of the tentpoles of the entire industry at this point, making up an increasingly large percentage of the total box office.

Speaking of superhero films, Suicide Squad and newcomer Dr. Strange rounded out the top 3 on the week with 90,484 and 65,488 tweets respectively. Suicide Squad has been in the top 10 for every week of 2016 so far so this was just business as usual for the aspiring franchise. Dr. Strange was here for the first time though as buzz about its impending first trailer reached 16,953 tweets on Wednesday. Next week it will debut during Jimmy Kimmel's late night show and I'll be very interested to see just how it stacks up with other superhero films, specifically Ant-Man which I think is one of the better comparisons.

The BFG debuted its first trailer on Tuesday which gave it 8,737 tweets, a promising start for the Stephen Spielberg adaptation of Roan Dahl's beloved book. By comparison, the first trailer for Paddington had 2,500 tweets.

Rogue One: A Star Wars Story also debuted a trailer yesterday but we were only able to capture a partial total for its day and as such it did not land in the top 10. It will turn up next week in the list no doubt as today alone it is at over 30,000 and leading all tracked films.
